WARREN J. BALL, OF LEETONIA, OHIO.

NIOLDERS FLASK-PIN.

SIEECLIFICATION forming part of Letters Patent No. 726,242, dated. April28, 1903.

Application filed June 24. 1902.

To all whomI it may concern:

Be it known that I, WARREN J. BALL, a ci tizen of the United States,residing at Leetonia, in the county of Columbiana and State of Ohio,have invented certain new and useful Improvements in Molders Flask-Pins;and I do hereby declare that the following is a full, clear, and exactdescription of the same,.ref erence being had to the annexed drawings,making a part of this specification, and to the figures of referencemarke'd thereon, in which- Figure 1 is a perspective view showing aportion of a molders flask and the pin properly connected thereto. Fig.2 is a vertical section of the pin. Fig. 3 is a detached perspectiveview of the clamp, also showing the position of the cross-bolt. Fig.4isadetached perspective view of the pin. Fig. 5 is a detachedperspective -view of the clamp-lever.

The present invention has relation to molders flask-pins; and itconsists in the novel construction hereinafter described,andrparticularly pointed out in the claims.

Similar numerals of reference indicate cor-- responding partsin all theiigures of the drawings.

In the accompanying drawings, 1 represents the lower iiask-section, and2 the upper flask-section, said sections being formed in the ordinarymanner and within themselves form no particular part'of the presentinvention.

The object of the present invention is to provide a means for securingthe sections together in such a manner that the sections will not shiftor move with reference to each other at the time the upper flask-sectionis being rammed or filled.

Another object is to provide a means for easily removing the uppersection after it has been rammed or filled and afterward hold thesections together at the time a casting is made.

To the lower flask 1 and at the ends thereof are connected twoiianges,such as 3, which flanges are provided with the right-angled portions 4,which right-angled portions are provided with notches or openings 5 toreceive the pin 6. To the upper iiask 2 is attached the iiange 7, whichflange is provided with the inclined face 8 and the elongated slot 9,the elongated slot being for the purserrano. 112,990. (No model.)

pose of receiving the headed bolt 10, which headed bolt is locatedsubstantially as shown in Figs. 2 and 3; also illustrated in Fig. 1. Thepin 6 is provided with the head 1l, the inner face'of said head beingprovided with an inclined face 12, which inclined face is locatedadjacent and against the inclined face 8 of the iiange 7, and-for thepurpose of assisting in holding the head 1l in proper relative positionto the iiange 7 and its inclined face the guide-flanges 13 are provided,said iianges being for the purpose of preventing the swinging of the pinupon the bolt 10. The head 11 is provided with the inclined-faced disk14, which inclined-faced disk is located around the aperture 15. 6 isprovided with an inclined face 17, which inclined face is substantiallythe same as that of the inclined face 14, said faces being for thepurpose hereinafter described. Upon the bolt 10 is located'a nut 18,and, if desired, a

Ywasher 19 maybe vr-located upon the bolt between the head of the lever16 and the nut 18`; but this is not absolutely necessary, as it will beunderstood that the nut 18 may be brought into operativefcontaet withthe head of the lever 16, and, if desired, a second nut 20 may belocated upon the bolt-10; but this is simply a question of judgment.

In use the flasks or secti ns 1 and 2 are placed together in the usualmanner, reference being had to the iilling and ramming of the sectionsand the pinA 6 '(one at each end of the flask) is slipped in the notchor opening 5 and its head slid down the incline of the iiange 8 untilthe pin is seated against the face of the notch 5, after which the lever16 is turned in the direction to bring the pin 6 in proper position withreference to the notch oropening 5 to securely hold the flask-sections 1and 2 together and in such a manner that there is no movement of oneiiask-independent of the other. At the timethecasting is made the pinsare seated into Ithe notches or openings, so thatthere is no danger ofany springing of the flask-sections one upon the other.

It will be understood that my peculiar arrangement at the time the upperflask is being treated, before the casting is made, there can be norelative movement between the two flask-sections.

It will also be un- The clamping-lever IOO derstood that by my peculiar'arrangement when the lever 16 is turned so as to release the pin o thepin will be free to swing in a limited sense, so that there is no dangerof breaking the pin if in the event the flasks 2 and 3 are not parteduniformly throughout their entire length, or, in other words, one end ofthe upper llask can be elevated regardless of the opposite end withoutdanger of breaking the flask-pins.

It will be understood that by providingr the elongated slot 9 the bolt10, together with the pin 6 and the different parts located upon thebolt, can be moved up and down, and when moved upward the pin 6 will becarried away from the right-angled flange having the openings, and whenmoved down the pin 6 will be brought toward the flange 3 andinto theopening 5.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a device for securing the sections of a molders flask together, aflange provided with an inclined face, said flange secured to one of theflask-sections, a llange provided with an angled portion having a recessor opening, said flange secured to the other flasksection, a pinprovided with a head having an inclined face and an inclined disk,aclamplever havingr an inclined-faced head and a bolt adj ustablysecured to the flange having the inclined face, substantially as and forthe purpose specified.

2. The combination of upper and lower flask-sections, the upper oneprovided with flanges having inclined ways, pins provided with headshaving inclined faces corresponding with the angle of theinclinedways,flanges located upon the lower flask-section and provided withright-angled portions having notches or openings, and said pins providedwith curved inclined faces, and levers provided withcorrespondingly-curved inclined faces, and clam ping-bolts locatedthrough the flanges having the inclined ways, the pins and theclamping-levers, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

WARREN J. BALL.
